'lO ALL WHOM IT MAY CONCERN:

Be it known that I, PE'ER BRUSQ, of the city of Erie, in the State of Pennsylvania, have inventeda new and useful Improvement in Electro-Magnetic Batteries; and I hereby declare that the followingis a full and exact description thereof, reference being had to'the accompanying drawings, in vwhich Figure 1 is al perspective view of two cups of a Grove battery, with my improvement represented in-,use

' thereon and Figure 2 is a longitudinal section of the arm A detached. My improvement consists in the employment of au adjustable larm for connecting the positive with the negative metal o1' poles of batteries, said arm being constructed with a binding-clampfor holding the platinum,

`and with an adjustable yoke or jaws for connecting with the zinc; and`is especially designed to be used with, the Grove battery when a. series of cups or cells is employed. Invsuch batteries the platinum plate a, which is immersedfiin the acid of the' porous cell B, is'usual'ly connected by soldering with a slip of copper extending to the arm d of the zin'c or positive metal C, to which it is also soldered. In order to replenish the acid ofthe porous cell the platinum plate has to be occasionally removed, which is accomplished by bending the.copper connection. The frequency wthwhich this is required causes the soldered joint,or the copper, or platinum v t'o fracture in part or whole, and thereby interfereswith or entirely stops the action of the battery;A besides, as the zinc is soon dissolved, tlie frequency with which these connections have vto bc soldered anew entails' a large expense.

It is the object of my invention to overcome 'these lobjections by so constructing the connectionbetween the zincV und platinum that it may be readily changed when a new zinc: or positive met-al is required, .and adjusted to suit the distance between thecups and the depth of immersion of the platinum, and which will also admit ofithe removal of the latter when the poi-ous cellis replenished' without risk or inconvenience. To this cnil I construct 'an arm, A, of bruss'or any suitable nietah, one end of which is provided with av cross-head havirg a slot or opening of sullicient size, in one direction to admit theplatinum nlate a.

This opening contains a sli ing-follower lplatefb, which is moved by the thumb-screw c, by tightening which' a gainst the platinum it is held in close connection with the arm. This'admits of raising or'lowering the platinum by simply loosening the screw u.y At Vthe opposite end of the arm I` providey a clamp or -yoke consisting gfA two logger-'ears ff mj jecting downwards, with suicient space between thennto receive the projecting ariud of the zinc. Through one-of these ears passes a thumb-screw, g, bytightening which the arm A and zinc are held in snch'close conneetion asV to insure perfect conduction. This arrangemcnt'secules the'following advantages: It admits of the platinum/platebeng adjusted to thedistance between thescveral cups E ofht/he battery by moving the clamp ffg alongv the horizontal arm OQ the zinc. It enables 2the platinum-i to be easily removed from the porous cell by raising it, as representednirl red lines, fig. 1' whemthenrm Alturns on the hearing of the clamp, the 'screw g, forming its axis, places it entirely out of the way during'the replenishing `of` the cell. Itenables the intensityvof the action of the battery to be regulated by increasing or diminishing theV immersion of the platinum,

-the urnr'A remaining at any angle `ut 4which'itmay he set: It insures perfect and uniform conduction of electricity',` and prevents accidents, which sometimes ariseffroin the soldered joint melting under the heat4 of the electric current when the conduction at the joint isimperfect. It greatly reduces the expenses of working the' batteries of extensive telegraphic lines.

What I claim, and desire to secure by Letters Paten-t, is j The adjustable connecting-arm A for the cups of electro-magnetic batteries, consisting of 'the pivoted tmchmentffg and sliding clamp for the platinum, constructed and ope-ratingv substantially as set forth.

' In witness whereof I have hereunto'signed my name in the rresence of two subscribing witnesses.
